I stand by my original advice: you should become a scuba instructor so you can offer your guarantee to these students, who can also be your patients. Your passion for inclusivity would be a real asset to the diving community.
But simply demanding that others offer your guarantee, no matter how much (in your world) you think such a demand is reasonable, is not going to convince anyone to obey you.
You know what they say: put up or...
Sigh. You know what they say about fighting with pigs. Gotta love the little attempt at an insult at the end.
The only one here looking to be obeyed seems to be you, as the untrained medical professional overriding the professional judgement of physicians and the medical education of their patients. But ultimately you are partially right about one thing. No matter how much (in your world) you think you are to be obeyed without question, you are unqualified, dangerous, and ultimately unlikely to convince people now that they realize this.
For those that are diabetic divers taking insulin, send me a PM if you would like some of the “guaranteed” strategies to make your diving safer from a medical perspective. For anyone with a medical condition (that would be almost everyone if we are honest), don’t let bully instructors keep you from diving or discourage you from being honest with your physician to learn some strategies to make your diving safer. If these bully instructors make you want to hide your conditions, consider taking your business elsewhere and spreading the word about them. You can ultimately become a better diver if you look for a different instructor, one that is willing to work as a team member with you and your physician
For the author of that post, you clearly have a bit of an over inflated ego. Clearly, nothing anyone says here will change that. You, as you say, can do what you want and refuse to teach people for simply having a medical condition, regardless of what a medical professional has determined. It doesn’t change the fact that you have an overinflated sense of self. You clearly feel more qualified than physicians to determine a whether a patient’s medical condition renders them suitable to dive. You are overstepping your bounds. As much as you like to think that you are, you are NOT trained or qualified/certified to render a medical judgement. You are, however, discriminatory. I wouldn’t be surprised if you refuse to teach women because they “bleed” and might pass out underwater from iron deficiency or refuse to teach people of African ancestry since they could have sickle cell and pass out and die. You have an incomplete knowledge base for medicine and the really dangerous part is you cannot recognize that. You are that diver that thinks they are good without the training/experience to know otherwise.
I encourage all trainee divers, with medical conditions or not, to look for an
instructor that knows their own limits. If your instructor cannot recognize these limits, they are dangerous to you and themselves. You are better off looking elsewhere.
Interestingly enough, I am formally trained and qualified to recognize personality traits/disorders. You should chat with your physician about cluster B personality traits.
